Application ledfFebruary 20, 1922. Serial No. 538,062.

To all 'whom t may concern:

Be it known that I, BONIFACE PETRIK, a Citizen of France, and aresidentof St.- Eh'enne, Loire, France, have invented cer- 9 tain newand useful Improvements in Sportng,Guns;-and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable othhrs skilled in the art to which it appertains tomake and use the same. reference hilg had to the Vaccompanying drawings,and to letters or figures of reference marked thereon, which form a partof this specifica- ,5 yIn my application for U. S. patent' Serial Nm581,015 a sporting gun is described in which a strap d pivots about twoaxes or tltmniohs integral with the barrel block and is fitted ingrooves provided in the interior I0 of the cheeks of the breech piece g.(Figsflsiend7,).v

.As the applicant has roved, the manu of thetwo trunnions'or pivots e1is a somewhat diilicult operation, since they are l with the barrelblock endit is neces- ,In Jthat they should be accurately centered.

o remedy this drawback the applicant ha devised improvements which formthe Su ject of the present invention, of which l0 lthe most importantconsists in making the pivots or trunnions integral rwith the strap andadapted to enter into holes provided in the cheeks of the vbreak partsof the breech, the sides of the strap engaging in two l5 groovesprovided in the side faces ofthe barrel block. This method permits ofthe strap being very easily manufactured, since it can be made of twoidentically similarl 1000B. l0 The new arrangement practically invertsthe position of the male and female organs forming the pivotingconnection between the stra the barrel block and the breech piece.

T e accompanying drawings illustrate an l5 example of the improvementsaccording to the invention:

Fig. vl is an elevation of the rear end of the barrel block of the gun.

Fi 2 is a vert-ical section on the line X- of Fig. 1.

Figs. 3, 4 and 5 are detail views showing the strap, respectively, infront elevation, in side elevation and in plan.

Fig. 6 shows in elevation, partly in section,

b5 the strap mounted on the break of the in dot and dash lines.

Fig. 6a is a plan of Fig. 6. p i i Fig. 7 isa section on the line Y-Y-of Fig. 6, the strap not being sectioned so as to show its mounting inthe break of the breech piece. Fig. 8 is a section corresponding to Fig.7 and showing the gun in the rclosed position. Figs 9 and 10 show,respectively, in side view and in plan the` cocking piece which isdisplaced by the strap when the breech piece is opened. l y

The pivoting connection between the barrel block C and the breakv g ofthebreech piece is obtained by the strap d1 consisting of two absolutelysimilar pieces which are dis osed symmetrically y.as shownin Fig.` 3.ach piece or half strap'fcll carries lthe pivot or trunnion c1 which isintegral-with it and which is very easily turned onth lathe. Thesetrunnions or"pivots'srue1 are breech piece, the barrel block being shownadapted to engage; in holes provided iii the sides of the break g of thebreech piece as shown in Fig., 7. f Also, the sides of the strap d1 arelitted in 'grooves D cut on each of the lateral faces .of ,the barrelblock as shown'in F igs. 1 and` 2. grooves or Hats are of suilicientsize to allow thestrap d1 to engage while ltaking part in .therotational movement of the barrel block, as shown by the dot and dashlines in'Fig. 6.

The displacement of ytheY strap'fi1 is utilized to cock the gun. Forthis purpose the piece E acting as a cooking piece which is shown indetail in Figs. 9 and 10 has a projection H which engages in an apertureI of the strap d1 (Figs. 5 and 6). In these conditions when the breechis opened, that is to say when the barrel block is pivoted as shown inthe dot and dash lines of Fig. 6, the cooking piece E is displaced inthe direction of the `arrow F (Fig. 6) by the strap d1 which determinesthe cooking.

As shown in Figs. 3 and 5, the strap consists of two similar parts whichon the one hand facilitates its manufacture and the other hand allowsthe strap to be rapidly mounted in the break of the breech piece by thesimple engagement of each pivot or trunnion e1 in the corresponding holeof the side g. l

What I claim is 1. A sporting gun comprising a barrel block, a break,side cheeks secured to the These break, a removable strap providedbetween the barrel block and the break, grooves provided in the lateral'faces of the barrell lock, wherein the sides of the strap are engagedand means for permitting the pivoting o the whole device formed by thestra and the barrel lblock with reference to t Abreak. l

3.. sportl gun comprising a barre block, a brealllzg side cheeks securedto the break, a removable strapprovided between the barrel block and thebreak, grooves rovided in the lateral faces of the barrel b ock whereinthe sides 'of the stra are engaged, lateral trunnions secured to t esidesl of the strap, and holes provided in the internal facesof thecheeks of the break and having the saidftrunnions engaged therein.

4. A sporting "n comprising a barrel block, a break, s1 e cheeks securedto the block, a removable' strap formed in two etrical parts providedbetween the barrel block and the break, grooves vprovided in the lateralfaces ofthe barrel block where` in the sides of thestral are e i d,lateral trunnions secured tot e sides o the strap, and holes provided inthey internal faces of the cheeks of the break and having the saidtrunnions engaged therein.

5. A orting gun comprising a barrel block, a reak, side cheeks securedto the breaka Vremovable strapy rovided between the barrel block and thereak, means for securing the said strap to lthe, barrel block,

.the barrel block with reference to the for'cocking t e gun.

6. A s orting n comprising a barrel block, a freak, si e cheeks securedto the break, a removable strap provided between the barrel block andthe break, means for securing the said strap to the barrel block, andmeans for permitting the pivoting ofv the whole device formed by thestra and reak, means for transmitting the displacement of the stra withreference to the break, a slot provides in the back part of the strap,and a projection engaged therein and secured to.

the cooking mechanism.

7. A' sporting gun comprising a barrel block, a' break, vside cheekssecured to the break, a, removable strap provided between' the barrelblock and the break, grooves provided in the lateral faces 'of thebarrel block wherein the sides of the stra are engaged, lateraltrunnions secured to t e sides of the strap, and holes provided in theinternal faces of the cheeks ofthe break and having the said trunnionsengaged therein, a slot provided in the back part of the said strap, and,a projection provided in the said slot and secured to the mechanism forcooking the guns.` f

In testimony that I claim the foregoing as my invent1on,'I have signedmy name hereto.
